Description
Hazardous Rapid, Portaged at most flows!
This is the only Class V-VI rapid, and its portaged at most flows. If portaged on river left, you'll have a great view of the rapid, but have to seal launch to get back in. River right would be easier to portage if you have a raft. But we'll let you decide...
